What is the slope of the line through (-2,-6)and (2,2) HELP HELP HELP

After being rearranged and simplified, which of the following equations could be solved using the quadratic formula? check all that apply. a. 9% + 3x2 = 14 + x-1 b. -x+ + 4x + 7 = -32-9 c. 5x + 4 = 3x4 - 2 d. 2x2 + x2 + x = 30

What is the solution of the systems of equations? y=2/3x+3 x=-2

Give the equations of two different lines that are perpendicular to the line 3x + 4y = 7.
